I have since read that laptops may not support the game but thought I should mention this "fatal" problem I had. I am running a Toshiba 5200 series laptop with 2.2GHz, 512ram, GForceFX5600, P4, Windows XP Pro. The other night downloaded the 4th patch from the "3000AD" website where you log in with your serial number. I was playing the first level of the campaign when suddenly, my laptop crashed and received a windows stop message "PFN_LIST_CORRUPT" (Input/Output driver structure damage according to Microsoft). Tried to reboot and it from then on kept automatically trying to reboot. So I had no Alternative under the advise of the techies where I bought the laptop to restore my system. I did so using my recovery disks and now it won't boot at all. I get a "Disk Read Error". So whether it is the game patch's fault I do not know but thought it would be worth telling you. So for those laptop players...beware!
